Free Online Unit Converters

Unit converters make it easy to translate a measurement from one unit into another. Instead of remembering individual conversion factors, you can select the starting unit, enter a value and convert it into the measurement system you need.

Easy Calculator provides converters for common metric and imperial measurements as well as digital storage and specialist conversions.

Metric and Imperial Unit Conversion

Australia primarily uses the metric system for everyday measurements, but imperial units are still frequently encountered in international products, travel, building information, screen sizes and online content.

A unit converter can therefore be useful when converting measurements such as feet to metres, pounds to kilograms or acres to square metres.

Length Converter

Length describes the distance between two points. Common metric units include millimetres, centimetres, metres and kilometres, while imperial and US customary measurements commonly include inches, feet, yards and miles.

Some commonly used relationships include:

Weight and Mass Conversion

Kilograms and grams are commonly used for mass in Australia. Pounds and ounces are frequently used in countries that rely more heavily on imperial or US customary measurements.

Useful relationships include:

Temperature Conversion

Australia uses Celsius for everyday temperature measurement, while Fahrenheit is widely used in the United States. Kelvin is commonly used in scientific contexts.

Celsius to Fahrenheit

The formula is:

°F = (°C × 9/5) + 32

For example:

20°C = 68°F

Fahrenheit to Celsius

The formula is:

°C = (°F − 32) × 5/9

For example:

68°F = 20°C

Celsius to Kelvin

The conversion is:

K = °C + 273.15

Area Converter

Area measures the amount of two-dimensional space within a boundary. Area conversions are useful for property, flooring, land measurements, construction and international real estate listings.

Common units include:

• Square millimetres
• Square centimetres
• Square metres
• Square kilometres
• Square feet
• Acres
• Hectares

For example:

1 hectare = 10,000 square metres

Data Storage Converter

Digital storage measurements are used for files, memory, hard drives, mobile devices and cloud storage. Common units include bytes, kilobytes, megabytes, gigabytes and terabytes.

You may see both decimal and binary conventions used in computing, which can result in different values depending on the context.

Bra Size Conversion

Bra sizing is not completely standardised internationally. Band and cup labels can differ between Australia, the United Kingdom, the United States, Europe and other markets.

A bra size converter can provide a convenient comparison between common sizing systems, but actual garment fit may still vary between brands and styles.

Mouse Sensitivity Conversion

Mouse sensitivity settings can vary between games because different titles use different sensitivity scales and field-of-view behaviour. A sensitivity converter can help produce a comparable starting point when moving from one supported game or configuration to another.

Individual preference, mouse DPI, resolution and field of view can still affect how the converted sensitivity feels.

Which Unit Converter Should I Use?

• Use the Length Converter for metres, feet, inches, kilometres and other distance units.
• Use the Weight Converter for kilograms, pounds, grams and ounces.
• Use the Temperature Converter for Celsius, Fahrenheit and Kelvin.
• Use the Area Converter for square metres, square feet, hectares, acres and other area measurements.
• Use the Data Storage Converter for bytes, KB, MB, GB and TB.
• Use the Bra Size Converter to compare common international bra sizing systems.
• Use the Mouse Sensitivity Converter for supported gaming sensitivity conversions.
